I don't think it is necessary to use those four letter words, asterisked or not, in ordinary conversation or debate, unless you are talking about the act of ****ing itself. (I use *s here to denote that many words can be substituted for the *s) Most of the time they are used, to convey emotion, in a violent and abusive way. Violence, whether verbal or physical, destroys the credibility of any argument or arguer and distracts from the ideas being debated.

My father told me once that when you have to resort to violence, to make your point, in an argument, you have lost the argument. I never forgot that, and I try to live by it, as best I can.
